Re: [CAD_CAM_EDM_DRO] Felt Way wipers on SEriesII ok.??.. was Re:Lubrication for CNC

Hello Lee,
You are right! Or you can put a small spacer below the old wiper body
and
put only a small stripe below the rubber part. This way you keep the
soluble oil out.

I have used felt on many different type of machines. (have not even a
clue
what is a series II) I use 4 to 6 mm thick semi hard felt I get from a
local
Wood factory where they use it for their Melamine press line which I
service.
In one occasion I got nothing so I bought a few typical east german
Honeker
felt hats. (only one is left as souvenir) Another good source were in
one occasion
winter boots out of felt. There are some oldtimer cars and hydraulic
pistons that use
felt as retainer, that material is of excellent properties.
If you use too soft felt it gets torn apart and gets pulled into the
ways.

The biggest felt wiper I have seen these days on a Swansey automatic
lathe from middle 60's 7/8" 22 mm thick.
The ways on it are hardened and like brand new, not any scratch.
But Lee, keep in mind to put a wiper in front of the felt.
You can use factory wipers (Kabelschlepp BAS18 28,..$per meter and 7 $/m
for the replacement
plus a lot for transport)
Leather, Polyurethane, or brass shim.
So sometimes the thing builds up pretty much. (2 weeks ago 1" because I
needed a spacer to pass
the lubrication fittings.)
Good Luck
